Required information Consider the flow of engine oil (cp = 2048 J/kg-K) through a thin-walled copper tube at a rate of 0.3 kg/s. The engine oil that enters the copper tube at an inlet temperature of 80C is to be cooled by cold water (Cp = 4180 J/kg-K) flowing at a temperature of 20C. It is desired to have an exit temperature of the engine oil not greater than 48C. The individual convective heat transfer coefficients on oil and water sides are 750 W/m-K and 350 W/m-K, respectively. A thermocouple probe installed on the downstream side of the cooling water measures a temperature of 36C for a double- pipe parallel-flow heat exchanger. Hot oil 80C Cold water 20C Determine the mass flow rate of cooling water. (Round the answer to two decimal places.) The mass flow rate of cooling water is kg/s. Determine the log mean temperature difference. (Round the answer to a single decimal place.) The log mean temperature difference is C. Calculate the area of heat exchanger, if the log mean temperature difference is 29.8C. (Round the answer to two decimal places.) The surface area of the heat exchanger is Ime
